單機除(chu)塵(chen)器內部(bu)構(gou)造(zao)：殼(ke)體：用(yong)鋼板焊(han)接(jie)和螺釘(ding)連接(jie)。包(bao)括橡(xiang)皮(pi)密封門、濾(lv)(lv)袋框支架、清(qing)(qing)(qing)(qing)灰(hui)聯動(dong)(dong)(dong)機構(gou)等(deng)。灰(hui)斗：為(wei)殼(ke)體的(de)一部(bu)分，帶抽(chou)出(chu)式(shi)(shi)(shi)集塵(chen)抽(chou)屜。密封：為(wei)密性材(cai)料。濾(lv)(lv)袋：用(yong)208滌輪(lun)絨布(bu)制(zhi)(zhi)作，包(bao)括框架密封體和彈簧式(shi)(shi)(shi)內插墊。清(qing)(qing)(qing)(qing)灰(hui)機械(xie)：電力(li)產生高頻振動(dong)(dong)(dong)由偏心(xin)聯動(dong)(dong)(dong)機構(gou)傳送至濾(lv)(lv)袋進行(xing)清(qing)(qing)(qing)(qing)灰(hui)。控制(zhi)(zhi)：有風(feng)(feng)(feng)機和清(qing)(qing)(qing)(qing)灰(hui)民機的(de)直(zhi)接(jie)起動(dong)(dong)(dong)器和控制(zhi)(zhi)清(qing)(qing)(qing)(qing)灰(hui)周(zhou)期用(yong)的(de)時(shi)間繼電器。清(qing)(qing)(qing)(qing)灰(hui)機構(gou)可手(shou)動(dong)(dong)(dong)或自(zi)(zi)動(dong)(dong)(dong)控制(zhi)(zhi)。自(zi)(zi)動(dong)(dong)(dong)清(qing)(qing)(qing)(qing)灰(hui)在(zai)(zai)風(feng)(feng)(feng)機運行(xing)過(guo)程(cheng)中間歇進行(xing)。手(shou)動(dong)(dong)(dong)清(qing)(qing)(qing)(qing)灰(hui)則在(zai)(zai)風(feng)(feng)(feng)機停止運行(xing)時(shi)清(qing)(qing)(qing)(qing)灰(hui)，清(qing)(qing)(qing)(qing)灰(hui)數十秒鐘立即自(zi)(zi)動(dong)(dong)(dong)停止。風(feng)(feng)(feng)機與電機直(zhi)聯的(de)離心(xin)式(shi)(shi)(shi)風(feng)(feng)(feng)機，風(feng)(feng)(feng)機葉輪(lun)經過(guo)動(dong)(dong)(dong)平衡。

所謂清(qing)(qing)(qing)灰(hui)單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)是以壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)(qi)(qi)作(zuo)為(wei)清(qing)(qing)(qing)灰(hui)氣(qi)(qi)(qi)源，單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)根(gen)據清(qing)(qing)(qing)灰(hui)用壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)(qi)(qi)的(de)(de)壓(ya)(ya)(ya)力(li)不(bu)同(tong)大致(zhi)分為(wei)高(gao)壓(ya)(ya)(ya)和低壓(ya)(ya)(ya)。單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)濾(lv)(lv)袋(dai)上(shang)方設(she)有噴(pen)吹(chui)(chui)管(guan)，每個(ge)(ge)噴(pen)吹(chui)(chui)管(guan)上(shang)有若干個(ge)(ge)噴(pen)吹(chui)(chui)孔，每個(ge)(ge)噴(pen)吹(chui)(chui)孔對(dui)準一(yi)(yi)個(ge)(ge)濾(lv)(lv)袋(dai)口，當單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)阻力(li)達規定(ding)值時，通過控(kong)制儀和電磁閥（或氣(qi)(qi)(qi)動閥）的(de)(de)作(zuo)用，開啟脈沖閥，壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)(qi)(qi)便在(zai)瞬(shun)間(jian)內通過文氏管(guan)并(bing)引射(she)幾倍(bei)于(yu)壓(ya)(ya)(ya)縮(suo)(suo)空(kong)(kong)氣(qi)(qi)(qi)量的(de)(de)周圍空(kong)(kong)氣(qi)(qi)(qi)一(yi)(yi)同(tong)射(she)向濾(lv)(lv)袋(dai)，使濾(lv)(lv)袋(dai)產生振動，加上(shang)逆氣(qi)(qi)(qi)流的(de)(de)作(zuo)用使濾(lv)(lv)袋(dai)上(shang)的(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)脫落(luo)下(xia)來，單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)從(cong)而(er)完(wan)成清(qing)(qing)(qing)灰(hui)過程。該(gai)類單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)每個(ge)(ge)脈沖閥帶一(yi)(yi)根(gen)噴(pen)吹(chui)(chui)管(guan)，每根(gen)噴(pen)吹(chui)(chui)管(guan)負責一(yi)(yi)排濾(lv)(lv)袋(dai)的(de)(de)清(qing)(qing)(qing)灰(hui)。所以也稱(cheng)之為(wei)行脈噴(pen)袋(dai)收塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)。單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)處理風量大、單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)系統阻力(li)小(xiao)、清(qing)(qing)(qing)灰(hui)、除塵(chen)(chen)(chen)(chen)(chen)等優點，在(zai)各企業(ye)   了廣泛的(de)(de)應用。如(ru)何進一(yi)(yi)步深入   單機(ji)除塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)清(qing)(qing)(qing)灰(hui)機(ji)理，不(bu)斷進行優化(hua)設(she)計顯得尤(you)其重要(yao)。

單(dan)機(ji)(ji)除(chu)塵(chen)(chen)器是治理大氣污染的(de)除(chu)塵(chen)(chen)設備。優點(dian)是除(chu)塵(chen)(chen)，實際應用(yong)中(zhong)其(qi)除(chu)塵(chen)(chen)效率可(ke)高達99.99％，排放濃度可(ke)控制在lOmg/m，以下(xia)甚至可(ke)達到lms/m3，正因為(wei)這些優點(dian)，已在很多中(zhong)   廣(guang)泛應用(yong)。但隨著(zhu)單(dan)機(ji)(ji)除(chu)塵(chen)(chen)器的(de)普及，單(dan)機(ji)(ji)除(chu)塵(chen)(chen)器粉塵(chen)(chen)爆炸事故也呈上升趨勢。單(dan)機(ji)(ji)除(chu)塵(chen)(chen)器解決潮濕(shi)的(de)注意事項如下(xia)：

1、慎用除塵(chen)布袋：應選用不易粘(zhan)湖的(de)光(guang)(guang)面(mian)除塵(chen)布袋，如光(guang)(guang)面(mian)滌綸濾料729、針刺氈(zhan)除塵(chen)布袋等。

2、較短的清(qing)灰(hui)周期：清(qing)灰(hui)周期短，有利于及(ji)時布袋表面石(shi)灰(hui)粉塵，減(jian)少粘結可(ke)能。

3、石灰粉除(chu)塵(chen)器設置旁路(lu)(lu)管(guan)道(dao)：當空(kong)氣(qi)相對濕度(du)時，進入(ru)除(chu)塵(chen)系統的含塵(chen)空(kong)氣(qi)很易(yi)結露，為(wei)避免(mian)水氣(qi)進入(ru)除(chu)塵(chen)器粘結濾料，應(ying)設置旁路(lu)(lu)管(guan)道(dao)，此時可(ke)避開除(chu)塵(chen)器，讓含塵(chen)空(kong)氣(qi)只通過(guo)旋(xuan)風(feng)除(chu)塵(chen)器，然后排入(ru)大氣(qi)。以上可(ke)采用(yong)自動控制。

4、較低的過濾(lv)(lv)風(feng)速：過濾(lv)(lv)風(feng)速較高(gao)，將迫使微細石(shi)灰(hui)粉塵進入內曲折微孔中(zhong)發生(sheng)堵(du)塞，反吹(chui)清(qing)灰(hui)不力時，長(chang)期停留于(yu)布(bu)袋內部而形成(cheng)粘結物堵(du)塞濾(lv)(lv)孔。而采用低過濾(lv)(lv)風(feng)速，可(ke)避免上述弊病。

5、足夠(gou)的(de)(de)清灰(hui)反(fan)吹(chui)壓(ya)力：用(yong)反(fan)吹(chui)風清灰(hui)，可(ke)將進入(ru)濾料(liao)中的(de)(de)石灰(hui)粉(fen)塵清洗出來(lai)，而足夠(gou)的(de)(de)壓(ya)力，有利于較清洗濾料(liao)中的(de)(de)粉(fen)塵。
